Description
Flame-proof, reinforced polycarbonate ABS moulding compositions The present invention relates to reinforced polycarbonate ABS moulding compositions flame-proofed with organic phosphorus compounds which have an excellent mechanical property level.
Reinforced flame-proofed polycarbonate ABS moulding compositions are already known.
Inter alia, EP-A-0 754 531 describes flame-proof moulding compositions consisting of polycarbonate, ABS graft polymer and optionally SAN copolymers which are reinforced with foliate inorganic materials.
Flame-proof polymer mixtures consisting of aromatic polycarbonate, styrene-containing copolymer and/or graft polymer, oligomeric phosphates as flame-proofing agents and fibres as reinforcing agents are known from EP-A-0 363 608.
The teaching of EP-A-0 640 655 relates to flame-proof moulding compositions consisting of aromatic polycarbonates, styrene-containing copolymers, graft polymers, and a mixture of mono- and oligomeric phosphates, which may optionally contain glass fibres as reinforcing materials.
For certain applications, such as for the production of moulded bodies with increased mechanical stress or for moulded bodies with thin wall thickness, the known moulding compositions exhibit an inadequate property level, particularly too little rigidity or insufficient flow behaviour.
The present invention provides flame-proof, reinforced polycarbonate ABS moulding compositions which have an excellent E modulus in Le A 32 466-Foreign addition to very good flame-proofness, very good processing properties and a high mechanical property level.
Surprisingly it has now been found that by the use of certain mixtures of polycarbonates, each with distinctly different solution viscosities, polycarbonate ABS
moulding compositions result which have a distinctly better E modulus, higher notch impact strength and better processing behaviour than moulding compositions which contain as polycarbonate component only a polycarbonate with a corresponding average solution viscosity.
The invention therefore provides flame-proof, reinforced thermoplastic moulding compositions, containing A. 5 to 95, preferably 10 to 90, particularly preferably 20 to 80 parts by weight of a mixture of two aromatic polycarbonates A. 1 and A.2 with different solution viscosity, wherein 1. the relative solution viscosity of A. 1 is 1.18 to 1.24, 2. the relative solution viscosity of A.2 is 1.24 to 1.34 and 3. the difference between the relative solution viscosities of A.1 and A.2 is not less than 0.06, wherein one or more further polycarbonates may be added to the mixture of A.1 and A.2, B. 0 to 50, preferably 1 to 30, particularly preferably 2 to 25 parts by weight of a vinyl (co)polymer consisting of one or at least two ethylenically unsaturated monomers, Le A 32 466-Foreign C. 0.5 to 60, preferably 1 to 40, particularly preferably 2 to 30 parts by weight of graft polymer with a glass transition temperature < - 10 C obtainable by graft polymerization of at least two of the monomers selected from chloroprene, butadiene, isoprene, styrene, acrylonitrile, ethylene, propylene, vinyl acetate and (meth)acrylic acid ester with 1 to 18 C atoms in the alcohol component, D. 0.5 to 20 parts by weight, preferably I to 18 parts by weight, particularly preferably 2 to 15 parts by weight, of phosphorus compound of fonnula (I) O ~ O 4 R'-(O)n-P O-X-O-P (O)n-R (I), (0)n (~)nll R- R3 'I N

The sum of all parts by weight A+B+C+D+E+F is 100.

The preferred graft base (3 consists of pure polybutadiene.
The de,QrPe of graft G denotes the weight ratio between grafted graft monomers and graft base and is dimensionless.
The average particle size d50 is the diameter above and below which 50 wt.% of the particles lie in each case. It may be determined by ultracentifuge measurement (W.
Scholtan, H. Lange, Kolloid, Z. und Z. Polymere 250 (1972), 782-796).

The graft polymers C may be produced by known processes such as bulk, suspension, emulsion or bulk-suspension processes.
Since in the graft reaction, the graft monomers are not necessarily completely grafted onto the graft base, as is known, according to the invention graft polymers C
are also understood to mean those products which are obtained by polymerization of the graft monomers in presence of the graft base.

They are also used in the field of electrical engineering because they have very good electrical properties.
A further form of processing is the production of moulded bodies by thermoforming from previously produced sheets or films.

The fire behaviour of the samples is measured according to UL-Subj.94V on rods of dimensions 127 mm x 12.7 mm x 3.2 mm and/or 1.6 mm.
The rods are mounted vertically in such a way that the underside of the test body is located 305 mm above a strip of bonding material. Each test rod is individually ignited by means of two successive ignition processes each of 10 seconds' duration.
The combustion properties after each ignition process are observed and the sample then evaluated. A Bunsen burner with a 10 mm (3.8 inch) high blue natural gas flame Le A 32 466-Foreign with a unit of heat of 3.73 x 104 kJ/m3 (1000 BTU per cubic foot) is used to ignite the sample.
To assess the fire behaviour, a flame is applied to each test body twice, for 10 seconds on each occasion. The smoulder time is measured after the ignition source has been removed. Five test bodies are used for each test and the 10 individual bun.ling times and the sum of the individual smoulder times determined.
The composition of the materials tested and the data obtained are summarized in Table 1 below.

Producing and testing the moulding compositions according to the invention Components A to F are mixed with the conventional processing auxiliary substances on a ZSK 32 twin screw extruder. The moulded bodies are produced on an Arburg 270E type injection moulding machine at 260 C.
Notch impact strength is determined according to ISO method 180 1 A on rods of dimensions 80 x 10 x 4 mm3 at room temperature.
Heat deflection temperature according to Vicat B is determined to DIN 53 460 on rods of dimensions 80 x 10 x 4 mm3.
Tensile E modulus is detennined according to ISO 527/DIN 53 457.
Flame resistance is determined according to UL94V.
The fire behaviour of the samples is measured according to UL-Subj.94V on rods of dimensions 127 mm x 12.7 mm x 3.2 mm and/or 1.6 mm.
The rods are mounted vertically in such a way that the underside of the test body is located 305 mm above a strip of bonding material. Each test rod is individually ignited by means of two successive ignition processes each of 10 seconds' duration.
The combustion properties after each ignition process are observed and the sample then evaluated. A Bunsen burner with a 10 mm (3.8 inch) high blue natural gas flame Le A 32 466-Foreign with a unit of heat of 3.73 x 104 kJ/m3 (1000 BTU per cubic foot) is used to ignite the sample.
To assess the fire behaviour, a flame is applied to each test body twice, for 10 seconds on each occasion. The smoulder time is measured after the ignition source has been removed. Five test bodies are used for each test and the 10 individual bun.ling times and the sum of the individual smoulder times determined.
The composition of the materials tested and the data obtained are summarized in Table 1 below.
